One mystery that has followed me throughout my life is how to gain muscle mass and weight.

I have been skinny since childhood. Even now, I maintain a healthy BMI and the right weight for my height and age, but I still feel like my body doesn’t build muscle easily. No matter what I try, my weight has remained almost the same for the past six years, fluctuating by just one or two kilograms.

There’s a desire in me to achieve more stamina, more strength and more capable body.

What puzzles me the most is that I don’t fully understand my own body. Why does it resist change? Why is gaining muscle so difficult for me when others seem to do it more easily?

This has become a personal mystery I genuinely want to solve. Not just to change how I look, but to better understand how my body works.

And hopefully, someday soon, I’ll find the answer.
